[PMID: 38614015 DOI: 10.1016/j.injury.2024.111532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 03/25/2024] [Accepted: 04/01/2024] [Indexed: 04/15/2024]
Abstract
BACKGROUND Fixation of sustentaculum tali fractures is important to maintain the biomechanical function of the subtalar joint. A common method of fixation is securing the sustentacular fragment by way of a laterally based locking plate (LP). A medial approach with a single screw (MS) has been proposed as an alternative method of fixation. METHODS Five pairs of formalin-preserved cadaveric ankles with the subtalar joint and interosseous ligaments intact ("osseous cadavers") and four pairs of fresh-frozen cadaveric ankles with soft-tissue preserved dissected from mid-tibia down ("soft tissue cadavers") were used in the study. The left ankle was randomly assigned to one of the two fixation methods (LP or MS), while the right ankle was the opposite. These same steps for fixation were repeated for six synthetic ankle models. All models were loaded with a body mass of 80 kg. Statistical differences between LP and MS stiffness were determined using a paired t-test in cadavers and un-paired t-tests in synthetic ankles. RESULTS For osseous cadaveric ankles, LP demonstrated a mean stiffness of 232.95(SD: 59.96) N/mm, while MS was 239.72(SD:131.09) N/mm (p = 0.9293). For soft tissue cadaveric ankles, LP mean stiffness was 133.58(SD:37.84) N/mm, while MS was 134.88(SD:20.75) N/mm (p = 0.9578). For synthetic ankles, LP mean stiffness was 220.40(SD:81.93) N/mm, while MS was 261.50(SD:100.21) N/mm (p = 0.6116). CONCLUSIONS Across all three models, there was no significant difference between LP and MS methods. Retrospective observational studies are recommended to assess patient outcomes from each of the methods.

Abstract
BACKGROUND Optimal management of displaced intraarticular calcaneal fractures remains controversial. The aim of this prospective cohort study was to compare the clinical and radiologic outcomes of minimally invasive surgery vs nonoperative treatment in displaced intraarticular calcaneal fracture up to 2 years. METHODS All displaced intraarticular calcaneal fractures between August 2014 and January 2019 that presented to a level 1 trauma center were considered for inclusion. The decision to treat was made by a multidisciplinary team consisting of fellowship-trained orthopaedic surgeons. Operative treatment protocol involved sinus tarsi approach or percutaneous reduction and internal fixation. Nonoperative protocol involved symptomatic management with no attempt at closed reduction. The Manchester-Oxford Foot Questionnaire (MOXFQ) and EuroQol-5 Dimensions-5 Level (EQ-5D-5L) patient-reported outcome measures were used to assess foot and ankle and general health related quality of life outcomes, respectively, at 2-year follow-up. Radiographic assessment was performed based on preinjury and 12-week postinjury radiographs. RESULTS A total of 101 patients were included for analysis between August 2014 and January 2019. We propensity score matched 46 patients in the surgical cohort to 46 patients in the nonsurgical cohort. At 24 months, there was no significant difference in the MOXFQ Index score (P > .05); however, the surgical cohort had a significantly higher EQ-5D-5L Index score (P < .05) and return to work (91% vs 72%, P < .05) and physical activity rate (46 vs 35%, P < .05) despite a higher proportion of more complex fractures in the surgical cohort. The wound complication rate following surgery was 16%. In addition, 14% of patients in the nonoperative cohort subsequently underwent arthrodesis compared with none of the patients in the surgical cohort. CONCLUSION In this study, we found that operative treatments were associated with low rates of surgical complication at 2 years and long-term pain improvement, facilitating earlier and better functional outcomes for complex injury patterns compared with nonoperative treatment for less severe fractures. LEVEL OF EVIDENCE Level III, retrospective cohort.

[PMID: 38443993 PMCID: PMC10916136 DOI: 10.1186/s13018-024-04606-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 01/31/2024] [Indexed: 03/07/2024] Open
Abstract
BACKGROUND This work investigated the differences in the biomechanical properties of open reduction and internal fixation (ORIF) and percutaneous minimally invasive fixation (PMIF) for the fixation of calcaneal fractures (Sanders type II and III calcaneal fractures as examples) through finite element analysis. METHODS Based on CT images of the human foot and ankle, according to the principle of three-point fixation, namely the sustentaculum tali, the anterior process and the calcaneal tuberosity were fixed. Three-dimensional finite element models of Sanders type II and III calcaneal fractures fixed by ORIF and PMIF were established. The proximal surfaces of the tibia, fibula and soft tissue were constrained, and ground reaction force and Achilles tendon force loads were added to simulate balanced standing. RESULTS The maximum stress was 80.54, 211.59 and 113.88 MPa for the calcaneus, screws and plates in the ORIF group and 70.02 and 209.46 MPa for the calcaneus and screws in the PMIF group, respectively; the maximum displacement was 0.26, 0.21 and 0.12 mm for the calcaneus, screws and plates in the ORIF group and 0.20 and 0.14 mm for the calcaneus and screws in the PMIF group, respectively. The values obtained from the simulation were within the permissible stress and elastic deformation range of the materials used in the model, and there was no significant stress concentration. The maximum stress and displacement of the calcaneus and implants were slightly lower in the PMIF group than in the ORIF group when fixing Sanders type II and III calcaneal fractures. CONCLUSIONS This study may provide a reference for optimising the design of implants, the development of individualised preoperative plans and the choice of clinical surgical approach.

Abstract
This comprehensive review delves into the multifaceted landscape of calcaneal fractures, thoroughly examining their aetiology, clinical presentation, and diverse management strategies. Encompassing surgical and non-surgical approaches, the review scrutinises critical aspects such as patient compliance, rehabilitation protocols, and long-term follow-up considerations. Surgical modalities, propelled by recent innovations like minimally invasive techniques and advanced fixation materials, are juxtaposed with non-surgical interventions, emphasising the pivotal role of patient education and adherence to optimise outcomes. The synthesis of critical findings underscores the need for individualised care and multidisciplinary collaboration in clinical practice. Moreover, the review outlines recommendations for healthcare practitioners and identifies promising areas for future research, including biomechanical studies and telerehabilitation. This comprehensive exploration aims to contribute to the ongoing evolution of calcaneal fracture management, ultimately enhancing patient care and outcomes in this complex orthopaedic realm.

Primary arthrodesis versus open reduction and internal fixation following intra-articular calcaneal fractures: a weight-bearing CT analysis. Arch Orthop Trauma Surg 2024; 144:755-762. [PMID: 38129717 DOI: 10.1007/s00402-023-05120-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Accepted: 10/29/2023] [Indexed: 12/23/2023]
Abstract
PURPOSE To compare primary arthrodesis (PA) versus open reduction and internal fixation (ORIF) in displaced intra-articular calcaneal fractures (DIACFs), based on clinical outcome and 2D and 3D geometrical analyses obtained from weight-bearing (WB) cone-beam CT images. MATERIALS AND METHODS In this prospective study, 40 patients with surgically treated calcaneal fractures were included, consisting of 20 PA and 20 ORIF patients. Weight-bearing cone-beam CT-images of the left and right hindfoot and forefoot were acquired on a Planmed Verity cone-beam CT-scanner after a minimum of 1-year follow-up. Automated 2D and 3D geometric analyses, i.e., (minimal and average) talo-navicular joint space, calcaneal pitch (CP), and Meary's angle (MA), were obtained for injured and healthy feet. Clinical outcomes were measured using the EQ5D and FFI questionnaires. RESULTS Overall, there were no differences in baseline patient characteristics apart from age (p < 0.005). The calcaneal pitch in 2D after treatment by ORIF (13.8° ± 5.6) was closer to the uninjured side (18.1° ± 5.5) compared to PA (10.9° ± 4.5) (p < 0.001). Meary's angle in 2D was closer to the uninjured side (8.7° ± 6.3) after surgery in the PA cohort (7.0° ± 5.8) compared to the ORIF cohort (15.5° ± 5.9) (p = 0.046). In 3D measurements, CP was significantly decreased for both cohorts after surgery (- 4.09° ± 6.2) (p = 0.001). MA was not significantly affected overall or between cohorts in 3D. Clinical outcomes were not significantly different between the ORIF and PA cohorts. None of the radiographic measurements in 2D or 3D correlated with any of the clinical outcomes studied. CONCLUSION Three-dimensional WB CT imaging enables functional 2D and 3D analyses under natural load in patients with complex calcaneal fractures. Based on clinical outcome, both PA and ORIF appear viable treatment options. Clinical correlation with geometrical outcomes remains to be established.

Abstract
PURPOSE Calcaneal fractures (CFs) are rare but potentially debilitating injuries. Apart from the open, far lateral or sinus tarsi approach, operative treatment can be performed minimally invasive and percutaneously with intramedullary nailing. In this study, we sought to investigate the functional outcome of severe CFs treated with the C-Nail® implant. METHODS Twenty-two CFs (9 × Sanders III and 8 × Sanders IV), operated between 2016 and 2019, were followed up with a mean duration of 36 (± 11) months. The AOFAS score, pre- and postoperative Böhler angles, wound healing disorders, and patient-reported outcome measures (PROMs) like pain levels and return to work/sport levels were assessed. RESULTS The mean AOFAS score was 72.0 (± 9.8). Four patients sustained wound healing disorders, yet no implant-associated surgical revision was required. Fifty percent of patients were pain-free within 1 year. Within 1 year, about 50% of the patients could return to sports, and about 80% of the patients could return to work. PROMs and functional results align with those from other implants reported in the literature. CONCLUSION Intramedullary nailing of severe CFs with the C-Nail® implant can be considered a safe treatment alternative that yields acceptable results at mid-terms.

Abstract
Background Primary subtalar arthrodesis (PSTA) is a valid option in treating Sanders IV calcaneal fractures with few studies to assess its outcomes. Methods Seventeen patients with Sanders IV calcaneal fractures were managed by open reduction and primary subtalar arthrodesis. Functional outcomes were measured by AOFAS-AHS and FAAM-ADL. We also documented time to return to work, union rate, wound complications and the need for second surgeries. Results Fourteen patients were followed for two years. At final follow-up, the mean AOFAS-AHS score was 74.42 ± 1.95, while the mean FAAM- ADL score was 59.21 ± 1.6. Conclusion PSTA is a valid option in treating these severe fractures. It may reduce the overall disability time.

Abstract
BACKGROUND Fractures of the calcaneus (heel bone) comprise up to 2% of all fractures. These fractures are mostly caused by a fall from a height, and are common in younger adults. Treatment can be surgical or non-surgical; however, there is clinical uncertainty over optimal management. This is an update of a Cochrane Review first published in 2013. OBJECTIVES To assess the effects (benefits and harms) of surgical versus conservative treatment of displaced intra-articular calcaneal fractures. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL, MEDLINE, Embase, and clinical trials registers in November 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing surgical versus non-surgical management of displaced intra-articular calcaneal fractures in skeletally mature adults (older than 14 years of age). For surgical treatment, we included closed manipulation with percutaneous wire fixation, open reduction with internal fixation (ORIF) with or without bone graft, or primary arthrodesis. For non-surgical treatment, we included ice, elevation and rest, or plaster cast or splint immobilisation. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. We collected data for the following outcomes: function in the short term (within three months of injury) or long term (more than three months after injury), chronic pain, health-related quality of life (HRQoL) and ability to return to normal activities, as well as complications which may or may not have led to an unplanned return to theatre. MAIN RESULTS We included 10 RCTs and two quasi-RCTs with 1097 participants. Sample sizes in studies ranged from 29 to 424 participants. Most participants were male (86%), and the mean age in studies ranged from 28 to 52 years. In the surgical groups, participants were mostly managed with ORIF with plates, screws, or wires; one study used only minimally invasive techniques. Participants in the non-surgical groups were managed with a plaster cast, removable splint or a bandage, or with rest, elevation, and sometimes ice. Risk of performance bias was unavoidably high in all studies as it was not possible to blind participants and personnel to treatment; in addition, some studies were at high or unclear risk of other types of bias (including high risk of selection bias for quasi-RCTs, high risk of attrition bias, and unclear risk of selective reporting bias). We downgraded the certainty of all the evidence for serious risk of bias. We also downgraded the certainty of the evidence for imprecision for all outcomes (except for complications requiring return to theatre for subtalar arthrodesis) because the evidence was derived from few participants. We downgraded the evidence for subtalar arthrodesis for inconsistency because the pooled data included high levels of statistical heterogeneity. We found that surgical management may improve function at six to 24 months after injury when measured using the American Orthopaedic Foot and Ankle Society (AOFAS) score (mean difference (MD) 6.58, 95% confidence interval (CI) 1.04 to 12.12; 5 studies, 319 participants; low-certainty evidence). We are not aware of a published minimal clinically important difference (MCID) for the AOFAS score for this type of fracture. Previously published MCIDs for other foot conditions range from 2.0 to 7.9. No studies reported short-term function within three months of injury. Surgical management may reduce the number of people with chronic pain up to 24 months after injury (risk ratio (RR) 0.56, 95% CI 0.37 to 0.84; 4 studies, 175 participants; low-certainty evidence); this equates to 295 per 1000 fewer people with pain after surgical management (95% CI 107 to 422 per 1000). Surgical management may also lead to improved physical HRQoL (MD 6.49, 95% CI 2.49 to 10.48; 2 studies, 192 participants; low-certainty evidence). This outcome was measured using the physical component score of the 36-Item Short Form Health Survey. We used a change in effect of 5% to indicate a clinically important difference for this scoring system and thus judged that the difference in HRQoL between people treated surgically or non-surgically includes both clinically relevant and not relevant changes for those treated surgically. There may be little or no difference in the number of people who returned to work within 24 months (RR 1.26, 95% CI 0.94 to 1.68; 5 studies, 250 participants; low-certainty evidence) or who require secondary surgery for subtalar arthrodesis (RR 0.38, 95% CI 0.09 to 1.53; 3 studies, 657 participants; low-certainty evidence). For other complications requiring return to theatre in people treated surgically, we found low-certainty evidence for amputation (2.4%; 1 study, 42 participants), implant removal (3.4%; 3 studies, 321 participants), deep infection (5.3%; 1 study, 206 participants), and wound debridement (2.7%; 1 study, 73 participants). We found low-certainty evidence that 14% of participants who were treated surgically (7 studies, 847 participants) had superficial site infection. AUTHORS' CONCLUSIONS Our confidence in the evidence is limited. Although pooled evidence indicated that surgical treatment may lead to improved functional outcome but with an increased risk of unplanned second operations, we judged the evidence to be of low certainty as it was often derived from few participants in studies that were not sufficiently robust in design. We found no evidence of a difference between treatment options in the number of people who needed late reconstruction surgery for subtalar arthritis, although the estimate included the possibility of important harms and benefits. Large, well-conducted studies that attempt to minimise detection bias and that measure functional outcomes using calcaneal-specific measurement tools would increase the confidence in these findings. Given that minimally invasive surgical procedures are already becoming more prevalent in practice, research is urgently needed to determine whether these newer surgical techniques offer better outcomes with regard to function, pain, quality of life, and postoperative complications for intra-articular displaced calcaneal fractures.

Pînzaru RM, Pavăl SD, Perțea M, Alexa O, Sîrbu PD, Filip A, Carp AC, Savin L, Forna N, Veliceasa B. Biomechanical Comparison of Conventional Plate and the C-Nail® System for the Treatment of Displaced Intra-Articular Calcaneal Fractures: A Finite Element Analysis. J Pers Med 2023; 13:jpm13040587. [PMID: 37108973 PMCID: PMC10141664 DOI: 10.3390/jpm13040587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/17/2023] [Accepted: 03/21/2023] [Indexed: 03/30/2023] Open
Abstract
The C-Nail® system is a novel intramedullary fixation method for displaced intra-articular calcaneal fractures. The aim of this study was to evaluate the biomechanical performance of the C-Nail® system and compare it with conventional plate fixation for the treatment of displaced intra-articular calcaneal fractures using finite element analysis. The geometry of a Sanders type-IIB fracture was constructed using the computer-aided design software Ansys SpaceClaim. The C-Nail® system (Medin, Nové Mesto n. Morave, Czech Republic) and the calcaneal locking plate (Auxein Inc., 35 Doral, Florida) and screws were designed according to the manufacturer specifications. Vertical loading of 350 N and 700 N were applied to the subtalar joint surfaces to simulate partial weight bearing and full weight bearing. Construct stiffness, total deformation, and von Mises stress were assessed. The maximum stress on the C-Nail® system was lower compared with the plate (110 MPa vs. 360 MPa). At the bone level the stress was found to have higher values in the case of the plate compared to the C-Nail® system. The study suggests that the C-Nail® system can provide sufficient stability, making it a viable option for the treatment of displaced intra-articular calcaneal fractures.

Abstract
BACKGROUND Calcaneal fractures can be high energy intra-articular injuries associated with joint depression. Challenges to fracture reduction include lateral wall blow out, medial wall overlap, comminution and central bone loss. Secondary deformity such as hindfoot varus alters foot biomechanics. Minimally invasive approaches with indirect reduction of the calcaneal tuberosity to maintain the reduction using posterior screws is routinely being used in the treatment of joint depression fractures. Biomechanically, optimum screw numbers and configuration is not known. Biomechanical studies have evaluated and proposed different screw configurations, however, it is not clear which configuration best controls varus deformity. This study aims to determine the optimum screw configuration to control varus deformity in Sanders 2B calcaneal fractures. METHODS Sawbone models were prepared to replicate Sanders type 2-B fracture, with central bone loss and comminution. 0.5 cm medial wedge of the calcaneal tuberosity was removed to create varus instability. After stabilising posterior facet with a single 4 mm partial threaded screw, and applied an 8 hole contoured plate to stabilise the angle of Gissane, inserted one or two 7 mm cannulated partially threaded CharlotteTM (Wright Medical Technology, Memphis, USA) Headless Multi-use Compression (under image guidance) extra screws to control varus and subsidence deformity of the fracture. Coronal plane displacement of the dissociated calcaneal tuberosity fragment relative to the body when applying 5 N, 10 N and 20 N force was measured in millimetres (mm). RESULTS 2 screws inserted (one medial screw into the sustentaculum talus from inferior to superior and, one lateral screw into the long axis anterior process) provides the least displacement (0.88 ± 0.390 at 5 N and 1.7 ± 1.251 at 20 N) and the most stable construct (p < 0.05) when compared to other configurations. A single medial screw into the sustentaculum tali (conf. 3) resulted in the least stable construct and most displacement (4.04 ± 0.971 at 5 N and 11.24 ± 7.590 at 20 N) (p < 0.05). CONCLUSION This study demonstrates the optimal screw configuration to resist varus in calcaneal fractures using minimally invasive techniques. Optimal stability is achieved using 2 screws; one located along the long axis of the calcaneus (varus control) and the other placed in the short axis directed towards the posterior facet of the calcaneus (control varus and subsidence). Further cadaver research would help evaluate optimal screw placement in simulated fractures to further assess reproducibility.

Effect of Intramuscular Tramadol on the Duration of Clinically Relevant Sciatic Nerve Blockade in Patients Undergoing Calcaneal Fracture Fixation: A Randomized Controlled Trial. Healthcare (Basel) 2023; 11:healthcare11040498. [PMID: 36833031 PMCID: PMC9957384 DOI: 10.3390/healthcare11040498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 02/05/2023] [Accepted: 02/06/2023] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND Calcaneal fracture fixation can generate severe postoperative pain and analgesia can be supported by a sciatic nerve block. However, following resolution of the sensory blockade, rebound pain may ensue. The aim of this study was to assess whether an incidental finding of two patients with an extension of the sciatic nerve block beyond 24 h following 100 mg of intramuscular tramadol administration could be confirmed. METHODS Thirty-seven patients scheduled for a calcaneal intramedullary fixation (Calcanail®) were randomly divided into two groups. The tramadol group (n = 19) received a sciatic nerve block with 20 mL of 0.25% bupivacaine and a concomitant dose of 100 mg of intramuscular tramadol, while the control group (n = 18) received an identical sciatic nerve block with concomitant injection of normal saline (placebo). All patients had a spinal anesthesia with light sedation for the procedure. The time to first analgesic request defined as appearance of any pain (NRS > 0) was assessed as the primary endpoint with a clinically relevant expected result of at least 50% elongation in sensory blockade. RESULTS The median time to first analgesic request from time of blockade in the tramadol group was 670 min compared with 578 min in the control group. The result was clinically not relevant and statistically not significant (p = 0.17). No statistical difference could be demonstrated in the time to first opioid request, although a trend for opioid sparing in the tramadol group could be seen. Total morphine consumption in the first 24 h was also statistically insignificant (the tramadol group 0.066 mg kg-1 compared with 0.125 mg kg-1 in the control group). In conclusion, intramuscular tramadol does not extend the duration of analgesia of a sciatic nerve block following a calcaneal fracture fixation beyond 2 h and an opioid sparing effect could not be demonstrated in this trial.

Abstract
Abstract
Calcaneus has an important functional role in walking, running, gait and transferring 80% of total weight. Due to the paramount role of the calcaneus in function, there is a trend toward ‘below knee amputation’ for such heel injuries, associated with complete loss of calcaneus. Complex calcaneal defects represent a reconstructive challenge, due to few reported cases in the literatures, limited surgical options, and lack of long-term outcomes. We present a young patient regaining near normal function, weight bearing and independent walking after sustaining complex hindfoot defect that resulted in total loss of the calcaneus secondary to a landmine blast injury managed by soft tissue reconstruction only without skeletal reconstruction.

Abstract
INTRODUCTION Postoperative pain control and achieving opioid-free anesthesia are major issues for surgically treated patients with calcaneal fractures. We evaluated the potential role of posterior tibial and sural nerve blocks as a part of multimodal pain control techniques in patients underwent open reduction and internal fixation (ORIF) of calcaneal fractures via extensile lateral approach. METHODS Forty-eight patients randomly allocated to receive either posterior tibial and sural nerve blocks with bupivacaine (peripheral nerve block (PNB) group) or normal saline, after induction of general anesthesia. Patients were assessed for pain intensity, Interval from entrance to the recovery room to the first request for analgesic, recovery room and ward morphine consumption, global satisfaction and morphine side effects. RESULTS PNB group had less pain score compared to sham block (SB) group at each time point measurement during recovery room stay. There was also significant difference between the 2 groups regarding the pain scores after 2, 4 and 6 h of the operation in the ward. Time to the first request for analgesic was significantly prolonged in the PNB group (P < 0.001). The recovery room and ward morphine consumption was significantly lower in the PNB group (P < 0.001). Global satisfaction in PNB group was significantly more than that of SB group. No complication related to the nerve block was detected at the first postoperative visit in the outpatient clinic. CONCLUSION Peripheral nerve block could result in less postoperative pain especially in the early hours after ORIF of calcaneal fractures and reduce opioid administration within the first 24 h following the surgery.

Predictive Factors of Poor Outcome in Sanders Type III and IV Calcaneal Fractures Treated with an Open Reduction and Internal Fixation with Plate: A Medium-Term Follow-Up. J Clin Med 2022; 11:jcm11195660. [PMID: 36233528 PMCID: PMC9572188 DOI: 10.3390/jcm11195660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 09/22/2022] [Accepted: 09/22/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Consensus on the treatment for severely comminuted calcaneus fractures has yet to be found. This study aims to analyze the functional and radiological short- and medium-term outcomes of displaced calcaneus fractures of type III and IV treated with ORIF, and to identify, if present, the early predictors of unfavorable outcomes. Methods: Thirty-three calcaneal fractures were included, 23 type III and 10 type IV, according to Sanders classification. AOFAS scales for ankle and hindfoot and SF-12 were used. Böhler and Gissane angles were analyzed before and after surgery. Results: The minimum follow-up was six years. The mean AOFAS score at six months was 16.5 points (24.2 ± 10.8 vs 10.8 ± 9.5; p = 0.03) with better outcomes in patients with Sanders type III fractures. This difference decreased in the subsequent follow-up. Likewise, the mental and physical score of SF-12 had the same trend. Two wound infections and no deep infections were recorded in the Sanders type III fracture group. Instead, in the Sanders type IV group, there were four wound infections and one deep infection. Conclusions: Clinical and radiological outcomes in Sanders Type III and Type IV calcaneus fractures treated with plate and screws were very similar in long-term follow-up. If ORIF provided better short- to medium-term follow-up in Sanders type III fracture, these benefits have been lost in six years. Polytrauma and psychiatric patients showed significantly lower clinical outcomes in long-term follow-up, appearing as the most reliable negative predictors.

Minimally Invasive Osteosynthesis of Intraarticular Calcaneus Fracture Augmented by Femoral Head Allograft: A Retrospective Study. Cureus 2022; 14:e28684.

Abstract
Aim: The aim of this retrospective study is to report the results of minimally invasive osteosynthesis when used for the treatment of intraarticular calcaneus fracture. This old technique is regaining popularity recently with the multiple advances added by different institutes when it is used in the management of intraarticular calcaneus fracture. Methods: Twenty-four patients who suffered from intraarticular calcaneus fractures between 2014 and 2019 were included. Twelve of them had Sanders II fractures (group A) and 12 had Sanders III + IV fractures (group B). The mean follow-up duration was 37.5 months. The mean age at presentation was 54.23 ± 12.48 years. The skin condition at presentation was poor (blood-filled blisters) in 25% of patients equally distributed between the two groups. The mean time to surgery was 5.6 days where patients with poor skin conditions were treated lately. The technique involved percutaneous ascending proximal-to-distal pinning of the calcaneus after reduction using a 2 cm mini-incision below the lateral malleolus and augmenting the fixation with femoral head cancellous allograft. The primary outcomes variables analyzed in this study are post-operative Bohler angle, post-operative Gissane angle, American Orthopedic Foot and Ankle Society (AOFAS) ankle/hindfoot score at long-term follow-up (Excellent>95, Good 75-94, Fair 51-74, poor 0-50), and the delta angle benefit score. The secondary outcomes included post-operative complications such as infection and osteoarthritis. Results: The radiological results showed significant improvement of Bohler angle from 6.09° ± 21.6 pre-operatively, to 31.79° ± 14.1 postoperatively with a p-value <0.001. An adequate reduction was achieved in 54.16% to 70.8% of patients. There is a trend to normalization of overcorrected fracture especially Sanders II with a mean reduction of 12,71° ± 11,88 at one year post-operatively (p=0.05). AOFAS score at the last follow-up shows 20.83% poor results (AOFAS<50), 50% fair results (AOFAS between 51-74), 16.67% good results (AOFAS 75-94), and 12.5% excellent results (AOFAS>95. The satisfaction rate was 83.3% (45.8% partially satisfied, and 37.5% fully satisfied). The incidence of superficial infection (wound inflammation and pin tract infection) was more prevalent in higher group B (40%) compared to group A (0%) with p=0.014. Other complications including osteoarthritis and varus deformity were found in 95.8% and 58.3% of patients respectively at three-year follow-up. Conclusion: The combination of minimally invasive osteosynthesis and femoral head allograft for the treatment of intraarticular calcaneus fractures seems to give fair to good functional results. Radiological data demonstrated that when the Bohler angle is over-reduced >40°, there was a tendency to autocorrection over time. This may be due to progressive depression of the angle over time as weight bearing is authorized; however, this must be analyzed carefully due to the low number of patients who were overreduced (seven patients). Our study demonstrates that this technique has a low early complication rate (especially low infection and soft tissue problems) but carries high long-term complications such as osteoarthritis and hindfoot varus.

Abstract
BACKGROUND Subtalar pain following intra-articular calcaneus fractures may be associated with disability, pain, and a negative impact on the quality of life. Salvage procedures as subtalar fusion are associated with further consequences as stiffness, altered ankle biomechanics, and adjacent articular overloading with degenerative changes. The objective of the present study is to evaluate the short-term effects of viscosupplementation with intra-articular hyaluronic acid (HA) on function and pain, in patients with painful subtalar joint after calcaneus fracture. METHODS We searched for patients who underwent osteosynthesis of intra-articular calcaneus fracture between January 2011 and July 2015 and were diagnosed during the follow-up with pain and subtalar osteoarthritis. Between January and December of 2018, 13 patients (50 ± 10 years) accepted to participate in this study and received intra-articular HA injections. Three consecutive doses of 20 mg of HA were administered within a week interval, through anterolateral injections into the subtalar joint. We prospectively evaluated the function using the ankle/hindfoot American Orthopaedic Foot & Ankle Society score (AOFAS) and level of pain using the visual analog scale (VAS) before the intervention and 4, 12, and 24 weeks after the first injection. RESULTS Hindfoot function improved with an increase of AOFAS from 55 ± 19 before the intervention to 88 ± 20 at the 24th week (P = .001). Similarly, we observed relief of pain during the 24 weeks following intra-articular hyaluronic acid injection, with a decrease in VAS from 8.3 ± 1.3 before treatment to 2.2 ± 3.0 at the 24th week (P = .001). CONCLUSION For patients experiencing pain and dysfunction with subtalar osteoarthritis after intra-articular calcaneus fracture, viscosupplementation with intra-articular HA may be associated with improvement in function and pain in the short term. Furthermore, patients with higher grades of osteoarthritis may have limited benefit in pain relief and function improvement. LEVEL OF EVIDENCE IV, Case series.

Abstract
OBJECTIVE The purpose of this study was to retrospectively evaluate patients who had open reduction, external fixation and bone cement implantation of open calcaneal fractures. METHODS The records of 14 patients with open calcaneus fractures from January 2015 to January 2019 were reviewed retrospectively. Clinical evaluations consisting of AOFAS, MFS and EQ-5D VAS scores and radiological evaluations consisting of the height, width and length of the calcaneus as well as Bohler's and Gissane angle performed at 3 months, 1 year and the last follow-up postoperatively. Time to surgery, wound complications were recorded. RESULTS Our study sample consisted of 9 males and 5 females with a mean age of 38.5 ± 9.8 years and a mean follow-up of 31.4 ± 7.7 months. The mean period from injury to surgery was 5.4 ± 1.9 days and the mean duration of hospitalization was 13.2 ± 4.5 days. The AOFAS, MFS and EQ-5D VAS scores were 92.5 ± 10.3, 84.1 ± 9.7 and 86.4 ± 15.1 respectively at the final follow-up. The Bohler's angle increased from (12.9 ± 3.1)° preoperatively to (28.5 ± 6.3)° at the final follow-up (P < 0.001), with the Gissane's angle from (104.5 ± 9.7)° to (116.4 ± 8.9)° (P < 0.001). One patients (7.1%) developed pin infections and one patient (7.1%) suffered from dorso-lateral hindfoot hypoaesthesia. There was complete fracture healing without secondary loss of reduction in all cases. CONCLUSION External fixation with bone cement implantation is a valid alternative treatment for the management of displaced open calcaneal fractures with a low rate of complications.

Abstract
INTRODUCTION An isolated sustentaculum tali fracture is a rare manifestation of orthopaedic injury involving the supporting bone of the middle calcaneal facet. Globally, the incidence is estimated to be less than 1% of all calcaneus fractures. PRESENTATION OF CASE We reported a 42-year-old man with persistent ankle pain and instability on the right foot following a week after a motorcycle accident. The Computed tomography evaluation showed an avulsion of the medial sustentaculum tali on the right calcaneus bone. An open reduction and internal fixation procedure was performed using two cannulated cancellous screws applied across the lateral wall through the sustentaculum bone medially. The subjective postoperative evaluation showed that the patient responded well and gradually returned to daily routine activities without pain and instability. DISCUSSION AND CONCLUSION Surgical approach using the cannulated cancellous screw to establish a firm fixation of sustentaculum tali fracture fragment into calcaneus bone and to prevent pathological movement.

Abstract
Introduction. The calcaneus is a tarsal bone which plays a major role in transferring weight from the lower leg down through the ankle joint onto the forefoot and toes. It participates in the formation of the outer and inner longitudinal arch of the foot and has a significant role in walking and transferring body weight. Calcaneal fractures most often occur by jumping, falling from a height, or less often, in traffic accidents. Calcaneal fractures can be extra-articular and intra-articular. Intra-articular fractures can entirely damage joint surfaces, which results in deformity and immobility of the foot. They can be extra-articular and intraarticular, when disruption of the entire articular surfaces, deformity, and weakness of the foot occur. Case report. This case report presents a 40-year-old male with an intra-articular calcaneal fracture. He was injured by falling from a height of 3 meters and sustained an intra-articular fracture type IIIAB where one fracture line went laterally and the other centrally over the posterior calcaneal facet. Surgery was performed on the sixth day after the injury. The prepared locking plate for calcaneus was adapted and fixed with spongy screws in relatively preserved joint fragments: sustentaculum tali, tuberositas lateralis calcanei and tuber calcanei. In this way, we ensured the position of the repaired fragments, and then we placed 4 more spongy screws inside the healthy bone tissue, which was enabled with the use of this plate. With this procedure, the calcaneal axis, i.e. the varus deformity, height, width, length and angles of the bone (Bohler's and Gissane's angle) were corrected. From day one, the patient started to move his toes, and on the third day the patient started to move the ankle and began to walk with the help of props with no support on the leg. Conclusion. The preoperative value of Bohler's angle is a significant correlation between the severity of the injury and displacement of fragments in intra-articular calcaneal fractures. The goal of the surgery was to restore the posterior calcaneal articular facet, avoid soft tissue infection and form a normal shape and position of a foot.

Abstract
Computed tomography (CT) is nowadays the cornerstone for fracture pattern delineation in calcaneal fracture, and for operative planning. It is often challenging for radiologists in generating clinically oriented and meaningful CT reports to the orthopedic surgeon. The article aims to review the commonly encountered calcaneal injuries and highlight the key points in the description of these injuries and implications of the underlying classification system with respect to the surgeon's perspective. A thorough understanding of the pathoanatomy and potential complications of calcaneal fractures also helps radiologists in tailoring the radiology report in contribution to overall patient's management and prognostication. By doing so, we suggest ways in which the radiologists can add value to the radiology report.

J Foot Ankle Surg 2021; 60:1038-1043. [PMID: 34039510 DOI: 10.1053/j.jfas.2021.04.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 02/04/2021] [Accepted: 04/04/2021] [Indexed: 02/03/2023]
Abstract
The choice of treatment for Sanders Type II and Type III calcaneal fractures remains controversial with unclear patient functional outcomes. A meta-analysis was done to compare the functional outcome of ORIF vs primary subtalar arthrodesis (PSA) according to American Orthopedic Foot and Ankle Score (AOFAS) hindfoot-ankle scores. The PubMed, Embase, and Cochrane Library Databases were searched by two independent evaluators. Fourteen studies met the eligible criteria. ORIF of 501 Type II and Type III fractures was compared to primary subtalar arthrodesis treatment of 57 Type II and Type III fractures. AOFAS for a mixed ORIF group of "Type II and III" fractures was 82.16 ± 1.58 at average follow-up of 25.3 months. For a mixed PSA group of "Type II and III" fractures, the AOFAS was 74.22 ± 2.45 at average follow-up of 28.0 months. This showed a difference between ORIF and primary subtalar arthrodesis of 7.94 points (95% confidence interval [CI] = 7.75-7.98; p value .004) favoring ORIF when adjusting for minimally invasive and percutaneous methods. Without adjustment, there was a difference of 6.54 points favoring ORIF (95% CI = 6.22-6.46; p value .017). In conclusion, while high-quality randomized controlled trials comparing ORIF to primary subtalar arthrodesis for Type II and Type III fractures would further elucidate superior treatment outcomes, this meta-analysis of available data shows a tendency for ORIF of Type II and Type III Sanders calcaneal fractures to have a better functional outcome at approximately 2 years postoperatively compared to primary subtalar arthrodesis.

Abstract
INTRODUCTION Gissane's crucial angle (GA) facilitates to diagnose calcaneal fractures, and serves as an indicator of the quality of anatomical reduction after fixation. The study aimed to utilise statistical shape models (SSM) for analysing the complex 3D surface anatomy of the calcaneus represented by the simplified GA measurement on lateral radiographs. MATERIALS AND METHODS SSMs were generated from CT scans of paired adult calcanei from 10 Japanese and 31 Thai specimens. GA measurements in 3D and 2D were obtained for the lateral, central and medial anatomy of the posterior facet and sinus tarsi. The correlation between calcaneal length and GA was analysed. Regression and principal component (PC) analyses were conducted for analysing morphological variability in calcaneal shape relating to GA. The bilateral symmetry of the obtained measurements was analysed. RESULTS The mean GA (lateral) for the Japanese specimens was 105.1° ± 7.5 and 105.4° ± 8.5 for the Thai. The projected 2D angles of the central and medial measurements were larger (P < 0.00) than the 3D values. The medial projected 2D angles were larger (P ≤ 0.02) compared to the lateral. Despite the bilateral symmetry of GA and calcaneal length, their correlation displayed clear signs of asymmetry, which was confirmed by regression and PC analyses. CONCLUSIONS Japanese and Thai specimens revealed lower GAs (both range and mean) compared to reported reference values of other ethnicities. As a reduced GA is generally indicative of a calcaneal fracture, our results are important to surgeons for their diagnostic assessment of Japanese and Thai patients. The results indicate that the GA measurement on a plain radiograph is a simplified representation of the lateral-to-central 3D calcaneal anatomy but significantly underestimates the angle measurement on the medial aspects of the respective surface areas.

Abstract
OBJECTIVE This study aimed to determine the effectiveness of calcium phosphate cementing in the surgical treatment of Sanders type II and III calcaneal fractures using screw fixation with sinus tarsi approach. METHODS In this retrospective study, 85 feet of 84 patients (74 males, 10 females; mean age 43 [17-61] years) in whom screw fixation was performed using the sinus tarsi approach for Sanders type II or III calcaneal fractures were included. The mean follow-up was 28 (14-39) months. Patients were categorized into 2 groups on the basis of whether calcium phosphate cement (CPC) was used. Group 1 had 37 patients with CPC (38 calcaneal fractures) and group 2 had 47 patients without CPC (47 calcaneal fractures). In the clinical assessment, the American Orthopedic Foot Ankle Society (AOFAS) hind foot score and the Maryland Foot Score (MFS) were used at the final follow-up. In the radiological assessment, Bohler's angle on plain radiograph and posterior facet step-off on computed tomography were measured pre-and postoperatively. RESULTS At the final follow-up, the mean Bohler's angle was 26.2° (20°-33°) in group 1 and 26° (17°-30°) in group 2 (P = 0.85). The mean posterior facet step-off was 1.6 (0-5) mm in group 1 and 1.5 (0-5) mm in group 2 (P = 0.85). The mean AOFAS score was 83.8 (59-100) in group 1 and 85.8 (60-100) in group 2 (P = 0.5). The mean MFS was 86.3 (66-100) in group 1 and 87.7 (66-100) in group 2 (P = 0.62). CONCLUSION Evidence from this study have shown that CPC may have no significant effect on clinical and radiological outcomes in the surgical treatment of Sanders type II and III calcaneal fractures using screw fixation with sinus tarsi approach.

Abstract
BACKGROUND Classification of the type of calcaneal fracture on CT images is essential in driving treatment. However, human-based classification can be challenging due to anatomical complexities and CT image constraints. The use of computer-aided classification system in standard practice is additionally hindered by the availability of training images. The aims of this study is to 1) propose a deep learning network combined with data augmentation technique to classify calcaneal fractures on CT images into the Sanders system, and 2) assess the efficiency of such approach with differential training methods. METHODS In this study, the Principle component analysis (PCA) network was selected for the deep learning neural network architecture for its superior performance. CT calcaneal images were processed through PCA filters, binary hashing, and a block-wise histogram. The Augmentor pipeline including rotation, distortion, and flips was applied to generate artificial calcaneus fractured images. Two types of training approaches and five data sample sizes were investigated to evaluate the performance of the proposed system with and without data augmentation. RESULTS Compared to the original performance, use of augmented images during training improved network performance accuracy by almost twofold in classifying Sanders fracture types for all dataset sizes. A fivefold increase in the number of augmented training images improved network classification accuracy by 35%. The proposed deep CNN model achieved 72% accuracy in classifying CT calcaneal images into the four Sanders categories when trained with sufficient augmented artificial images. CONCLUSION The proposed deep-learning algorithm coupled with data augmentation provides a feasible and efficient approach to the use of computer-aided system in assisting physicians in evaluating calcaneal fracture types.

Abstract
Calcaneal fractures are the most common fracture of the tarsal bones and represent 1% to 2% of all fractures. Roughly 75% of these fractures include intra-articular involvement of the posterior facet of the calcaneus. Intra-articular calcaneal fractures are challenging injuries to manage for both patients and surgeons given their association with both early and late complications. This article aims to review the management, classification systems, surgical approaches, and care regarding intra-articular calcaneal fractures. A review of the current literature yielded treatment strategies that aim to reduce complications such as soft tissue injury or loss of articular reduction while maintaining satisfactory clinical outcomes. The purpose of this article is to review these current concepts in the management of intra-articular calcaneal fractures. Level of Evidence: Level V, expert opinion.

Abstract
PURPOSE The clinical and radiological results of locked plate osteosynthesis with an extensive lateral approach without bone graft in Sanders type III and IV intra-articular calcaneus fractures and the factors affecting these results were evaluated retrospectively. METHODS A total of 61 patients with Sanders type 3 and 4 calcaneus fractures who underwent a lateral approach with locked plate osteosynthesis were included in the study. The mean follow-up was 44.8 months. RESULTS The mean pre- and post-operative Gissane and Bohler's angles were 113.5° ± 13.9° and 106.7° ± 13.6° (p = 0.006) and 2.8° ± 14.1° and 19.6° ± 13.1° (p < 0.001), respectively. The mean post-operative AOFAS scores, SF-36, and Maryland were 80.5 ± 13.6 in type IIIAB, 89.4 ± 6.3 in IIIAC, and 82.4 ± 12.5 in IV; 58.6 ± 14.5 in type IIIAB, 60.3 ± 11.7 in IIIAC, and 58.0 ± 15.6 in IV; and 63.8 ± 7.2 in type IIIAB, 64.3 ± 7.1 in IIIAC, and 62.8 ± 11.7 in IV (p = 0.173, p = 0.932, p = 0.824, respectively). Wound problems were observed in 15 (28.6%) patients. Deep infection was not observed in any patient. CONCLUSION The clinical results were similar in type III and IV intra-articular calcaneus fractures applied with locked plate osteosynthesis in an extensive lateral approach and without the use of bone graft. Intra-articular calcaneus fracture fixation with a lateral locked plate is an effective treatment method.

Abstract
The bony and ligamentous structure of the foot is a complex kinematic interaction, designed to transmit force and motion in an energy-efficient and stable manner. Visible deformity of the foot or atypical patterns of swelling should raise significant concern for foot trauma. In some instances, disruption of either bony structure or supporting ligaments is identified years after injury due to chronic pain in the hindfoot or midfoot. This article will focus on injuries relating to the peritalar complex, the bony articulation between the tibia, talus, calcaneus, and navicular bones, supplemented with multiple ligamentous structures. Attention will be given to the five most common peritalar injuries to illustrate the nature of each and briefly describe methods for achieving the correct diagnosis in the context of acute trauma. This includes subtalar dislocations, chopart joint injuries, talar fractures, navicular fractures, and occult calcaneal fractures.

Abstract
Performing a thorough clinical evaluation following an acute displaced intra-articular calcaneal fracture is paramount for optimal surgical timing and long-term outcome. Initial survey must entail a comprehensive evaluation to rule out concurrent injuries. Focused lower extremity examination must involve a complete neurovascular and soft tissue evaluation to identify such conditions as compartment syndrome or compromised integument, which necessitate urgent intervention. Establishing baseline radiographs and advanced imaging is vital for surgical planning. Once deemed stable, protocol-driven treatment is best to ensure proper control of pain and edema and adequate management of economic and patient safety concerns.

Abstract
INTRODUCTION Calcaneal fracture is the most common foot fracture. It occurs due to an axial load and is associated with high morbidity, especially when the articular surface is involved. There are two types of calcaneal fractures: Joint depression type and tongue type. The latter has a high risk of skin necrosis and should be operated on promptly. CASE REPORT This is a 37-year-old Bangladeshi man who sustained a comminuted calcaneal fracture and a Lisfranc fracture of the left foot. Initial radiograph showed a joint depression-type fracture, excluding a surgical emergency. Nevertheless, the patient developed skin necrosis over the posterior aspect of the heal that improved after open reduction and internal fixation of the calcaneus. Pre-operative computed tomography (CT) scan demonstrated a bony fragment that was displaced posteriorly causing the skin necrosis. CONCLUSION X-ray imaging is not sufficient to exclude surgical emergencies with calcaneal fractures. Highly comminuted fractures should be assessed more thoroughly with urgent CT scan.

Abstract
Calcaneal fractures account for up to 75% of all foot fractures and 1% to 2% of all fractures. Approximately 75% of calcaneal fractures are intraarticular, resulting in a prolonged recovery, more pain, and disability. The most common mechanism of injury includes falls from a height and motor vehicle accidents. This article reviews studies that compare nonoperative with operative treatment. The literature continues to support surgical intervention; however, these injuries can still be managed nonoperatively in certain clinical scenarios. This article focuses on the surgical management of intraarticular calcaneal fractures and highlights the sinus tarsi approach.
